Answer 1

Resposta:

1) 44,8m

2) a) 20

b) 20

3) c= 40

p= 120

Explicação passo-a-passo:

1)

${h}^{2} = {c}^{2} + {c}^{2}$

${a}^{2} = {b}^{2} + {c}^{2} \\ {a}^{2} = {35}^{2} + {28}^{2} \\ {a}^{2} = 1225 + 784 \\ {a}^{2} = 2009 \\ a = \sqrt{2009} \\ a = 44.8$

2) a)

${h}^{2} = {c}^{2} + {c}^{2} \\ {h}^{2} = {12}^{2} + {16}^{2} \\ {h}^{2} = 144 + 256 \\ {h}^{2} = 400 \\ {h} = \sqrt{400 } \\ h = 20$

b)

${h}^{2} = {c}^{2} + {c}^{2} \\ {25}^{2} = {15}^{2} + {c}^{2} \\ 625 = 225 + {c}^{2} \\ 625 - 225 = {c}^{2} \\ {c}^{2} = 400 \\ c = \sqrt{400} \\ c = 20$

3)

${h}^{2} = {c}^{2} + {c}^{2} \\ {50}^{2} = {30}^{2} + {c}^{2} \\ 2500 = 900 + {c}^{2} \\ 2500 - 900 = {c}^{2} \\ {c}^{2} = 1600 \\ c = \sqrt{1600} \\ c = 40$

$p = h + c + c \\ p = 50 + 30 + 40 \\ p = 120$
